far, distant
迥 centers on being far away or distant, emphasizing spatial or metaphorical remoteness.
迥 combines the movement radical 辶 with 冋, which likely contributes the sound and the idea of distance or separation. The exact historical development is uncertain.
The movement radical 辶 suggests traveling, and the inner 冋 looks like a distant boundary or horizon. Picture walking a long path toward a far-off place.
For ケイ, imagine a distant kay (K) floating on the horizon: kay -> ケイ, and it is so far away it looks tiny.
